What we have is a semantic difference.
I think Joe's right. In the Hollywood Postproduction industry, it probably is the standard at this time. Although I recall a past time when WaveFrame may have had the edge, so changes may occur in the future.
Hollywood TV postproduction may well crash any Pro Tools student if he/she is not prepared. Putting new hires in the hot seat is one way to test their abilities, but it's more about testing their ability to work under pressure, not necessarily about how well he/she knows Pro Tools. That's a performance thing and is wholly different thing than knowing Pro Tools.
Some folks can learn to work "hot", "live" or whatever you want to call it, some can't. I know some studio folks who absolutely do NOT like mixing live. I know some who do both. I know some live sound people who know a lot about sound and have great ears, but are lost in front of Pro Tools.
It's a big world. "Can't we all just get along."
